Wireless Node Localization Based on Wild Goats Algorithm for Industrial Internet of Things

Abstract

In an industrial Internet of things (IIoT) environment, accurately determining the location of each sensor node is crucial for ensuring the data integrity of the network. Using the signal properties of the beacon nodes, an unknown node can calculate the distance to each beacon node and localize itself. Low computation time is important, particularly in an industrial environment, because many tasks need to be executed rapidly to maintain the timeliness of an industrial process. This paper proposes a node localization scheme based on the wild goats algorithm (WGA) to accurately and efficiently localize unknown nodes. The simulation results demonstrate the potential of the proposed localization algorithm to achieve better accuracy than other algorithms.
